Appnqatiou mea November 1e, 19ans.v siarnaeaaaa My invention vrelates to bearings. It is the object of my invention to provide a bearing which will be satisfactory purpose of supporting a shaft, and 'which 5 will also be of such a character that there will be no seepage or leaking of gases'or liquids along the bearing, 'from one portlon of the shaft to the other.-

My invention is particularlyadaptable forl bodying my invention, showing the construction thereof.

Referring to the drawings in detail, 1 1s the crank ease of the apparatus, which is provided with pistons 2, pitmen 3, and a crank shaft 4. This crank shaft is made of steel and is mounted, at-one end, in the crank case 1 in the usual bearing material 5. The bottom of the crank 'case 1s closed by a'support 6. The other end of the crank shaft rests in bearing material 7 within a crank case sleeve of cast-iron or steel 8. A shoulder-9 is formed on the. crank shaft, so that the portion 1Q of the crank is of greater diameter than the portion 11.

Adjacent this shoulder in the form of a ring 1s a steel collar 12, one side of which abuts against the bearing material 7, and thelother side of which abuts against a brass or bronze collar 13 surrounding the steel shaft. This collar is retained by an internally-threaded sleeve of steel 14 which is threaded at 15 on the outer end of the shaft 11. This brass or bronze sleeve 13 is provided with a groove 16 which is oppositely disposed from a second groove 17 within a' surrounding, co-operating, brass or bronze coll lar 18, which is carried within a cutaway portion 19 of the sleeve 8,l and against a shoulder 20 of the sleeve. Theouter end abuts against the internally-threaded sleeve 14.

' A hole 21 is drilled through the sleeve 8 in communication with the space formed by the ooves 16 and 17. The upper' end of ,this ole is provided with an internal thread 22 for sleeving 'the screw plug 23. This for the` vline of leakageis between those sleeves. lTh

v rounded by the ferrous metals.

` carried by said shaft having a groove, a sechole and the space in the grooves are filled with mercury, which forms an amalgam with' the brass or bronze sleeves 13 and 18, but which does not amalgamate with the ferrous material of the sleeve 8, the collar 14 and the ring 12. Theresult, however, is to provide a seal, due to this amalgamation, be-V tween the gases which maybe within the crank case 1 and the outside atmosphere, thereby preventing the exit of such gases.

The shaft 10 sup orted in the bearing 7 has pressed thereon Sie ring 12 of steelwhich turns therewith engaging the housin 8. The nonferrous sleeve 13 is also presse onthis shaft 10 abutting the ring 12 and is -70 held in` position by the sleeve 14 which'is" threaded upon the shaft 10 and turns Jwith it so that the yring 12 of steel, the non-ferrous sleeve 13 and the steel sleeve 14 turn together with the shaft. The non-ferrous'sleeve 18 carried in the housing 8 is stationar It is. driven finto the housing 8 and oes not turn therein.. The bearing surface is between the sleeve 18 and the sleeve 13v and any mercury is employed to seal this line of leakage becausey of its tendenc to amalgamate with the non-ferrous'meta s which are sur- It will be understood that I desire to comprehend within my invention such modifications as may be necessary to adapt lit to varyin conditions and uses. i

avin thus fully described my invention, what I c aim as new and desire to secure by Letters Patent, is

1. in combination, a chamber adapted to contain a gas, a bearing sleeve in the cham-V berl wall, ashaft mounted therein, a sleeve ond sleeve carried in said bearing sleeve hav'- ing a grooveoppositely disposed fromthe first mentioned grooye, mercury in said grooves, said sleeves being adapted to amalgamate with the mercu sageway throughJ the y caring sleeve and Y the second sleeve communicatmg with `the grooves for the introduction of mercury therein, means to seal said passageway, and

there being a pasretaining members f associated with said 1Q.

sleeves on said shaft. Y

2, In combination, a chamber adapted to contain a gas, a bearing sleeve in the chamber wall, a shaft mounted therein, a sl ve carried by said shaft having a groove, a i Il.

ond sleeve carried in said bearing sleeve having a groove oppositely disposed from the first mentioned groove, mercury in said grooves, said sleeves being adapted to amalgamate with the mercury there being a passageway through the bearing sleeve and the second sleeve communicating with the grooves for the introduction of mercury therein, means to seal said'passageway, and retaining members associated with said sleeves on said shaft, said retaining members consisting of a ring on one side abutting against a'shoulder on the shaft, and a threadedsleeve on the other side turning Within the bearing sleeve.

3. 'In combination, a crank case having gas l therein which it is desired to prevent from escaping therefrom, a crank shaft journalled in said crank case `supporting bearin `members for said crank shaft, a bearing s eeve, a shoulder on said crank shaft, a ring engaging said shoulder and also engaging the supporting bearing member in the bearing "sleeve, concentric sealing sleeves on said 25 shaft adjacent said ring, one of said concentric sealing sleeves beingY held in position by a shoulder in the bearing sleeve, a retaining sleeve carried by said shaft on the other side ofsaid concentric members, said concentric members having a reservoir for mercury therebetween adapted to amalgamate therenvith, mercury in said reservoir, said 4bearing sleeve having means for the introduction of mercury thereto, whereby the amalgamation between the concentric members and 4the amalgamating material will prevent the escmpe ofy gases in the crank case through the s eeve.

. 4. In combination, a chamber adapted to I contain a gas, a bearing sleeve in the chainber Wall, a shaft mounted therein, a sleeve` carried by said shaft having a groove, a second sleeve `carried in said bearing sleeve having a groove oppositely disposed from the first mentioned groove, mercury in said y, grooves, said sleeves being adapted to amalgamate with the mercury and retaining members associated with said sleeves on said shaft.

In testimony whereof, I aiiix my signature.
